Short of tightening all the leg joints, I don't know about finding the source of this type problem, but I have seen AM broadcast towers with copper jumpers wired across the leg joints to help prevent the same type of problem. The jumpers were connected with ring terminals soldered to copper braid, and the ring terminals were screwed to the legs with stainless steel sheet metal screws. The jumpers weren't weather proofed, oddly enough. I don't know if the jumpers were installed with the tower or if they were a cure for a problem that occurred after installation.
